PENCIL-HOLDER.

SPECIFICATION forming part of Letters Patent No. 392,536, dated November 6, 1888.

Application tiled J une 13, 188B.

.To @ZZ whom it may concern:

Be it known that I, OTTO BUssLER, a subject of the King of Bavaria, residing at Nuremberg, in the Kingdom of Bavaria, Germany, have invented certain new and useful Improvements in Pencil-Holders, of which the following is a specification.

My invention relates to improvements in pencil-holders.

The objects of my improvements are that on slightlypressing the head of the pencil-holder the lead contained therein is forced out, and when the pressure is released the lead is fastened in its position; but if a somewhat greater pressure is put upon the end the lead is left free from its grippers, and if the pencil-case be held up with the point downward the lead will fall out.

In order to make my invention clear, I refer to the accompanying drawings, which form part of this application, and in which similar letters denote similar parts throughout the different figures.

Figure l shows a section of my improved pencil-holdcr Without lead g Fig. l, a cross-section of same. Fig. 2 shows a cross-section of the same through the line a. 6, Fig. l. Figs. 2, 3, and 4t are sectional views showing the pencil-holder with lead. Figs. 5 and 6 are detail views of parts of the holder. Figs. 7, S, and 9 show modifications of the pencilholder, in which, instead ofthe separate spring 7L for holding the lead fast in the tube, the cap is slotted, and so forms a springgrip for the lead.

` In the outside case, A, which may be made from wood7 metal, or any other suitable material, are the three tubes a, b, and o. The tube a carries the transporting mechanism for the lead, which consists of two or more springs and the spring-claws e e, which are either part of the tube ct or fastened to it. The number of the claws e e can be two or more. Fig. l*L shows three and Fig. 2 two. For clearness in the drawings, in Figs. l to 4C, the claw c is placed opposite to the transportingspring h, so that the method of operation can be clearly explained.

The tube a slides over the tube b, and the amount that it slides is governed by the collar Z on b. The tube a is provided on its outside Serial No. 276.908. (No model.)

with a ring, g, which when the tube is moved forward abuts against the ring t iitted to the inside of the outer case, A, and thus prevents the tube a from further movement.

The tube b is provided at its top end with three or more slits, and provided with a spring, h, which can either be of the same piece as the tube b or riveted or soldered onto the same.

The claws e e of the tube o pass through the slits mentioned. The tube l) is further provided with the two collars Zand Z. The collar Z rests against the ring m of the part A of the outside case. On the tube b, between the collarsZZ and the ringm, is a spiral spring, f, coiled, which draws the tube b into the case A.

In the tube b is a second tube, c, in which the lead eZ fits. This tube c is joined to the pressing-cap lo by the pin a. Between the collar Z and the cap lc is a spiral spring, f', on the tube Z. The spring f is stronger than the spring f. rIhe end of the tube bis provided with the slits s s, through which the pin a passes. The pin a can move the length of the slits s s when the cap Zt is pressed, being fastened to the same.

The working of the abovedescribed pencilcase is as follows: If the lead cZ is fastened in the holder A, as in Fig. 2, and the capslightly pressed, the weaker spring f is compressed, and the tube band tlietube a, which iits lightly over b, shoved from out the holder A, Fig. 3. When the pressure on the cap Zt is released,the tube b is pressed back again by the action of the spring f, and the claws c e pressed against the lead (Z, and the lead Z drawn from out the case. Repeated pressing of the cap L sends the lead d from out of the holder.V rIhe lead Z is prevented from falling either out of the case or back into the same by the spring h when the claws e o release their grip of the lead. When a greater pressure is brought to bear on the cap lc, so that both the springs f and f are compressed and the tube c forced forward in the tube b, Fig. 4C, and against the slits s s, the tube c presses against the spring Zt and so leaves the lead d free, and as the lead cZ is no longer held fast in the case'A, so can the same be let fall out of the case A or into the same at will.

The cap is provided with the projections ICO w, against which the end ol the tube c presses and opens the cap, Fig. 9, by which the lead can fall out or in of the tube c, the saine as before described.

5 The above-described peneil-holder possesses all the good qualities that are desired in a peneil-holder in which the lead can be adjusted at pleasure.

Having now fully described my invention,

1o what I desire to elaine, and secure by Letters Patent in the United States7 is- 1. In a pencil-holder, the outer ease, A,oon taining the three inner tubes, a, b, and c, in combinationwith the spiral springs f f', spring I 5 h, and claws e e, for the purpose as described.

2. In a pencil-holder, the tube a, having two or more elaws, e e, and the ring g, adapted to slide over the tube b, which is provided with the spring h at its outer end, and the collars Z Z', in combination with the spiral springs ff', for 2o the purpose as described.
